===== DLS ADSR ===== | |||
MusyX can also express more advanced envelopes using a modified [[wikipedia:DLS format|DLS]] representation. | |||
This representation includes scaling coefficients to respond to played note and velocity | |||
(so slamming down a key harder plays longer). | |||
The attack and decay members are expressed in ''time-cents''. This may be converted to seconds using: | |||
<code>2<sup>timecents / (1200.0 * 65536.0)</sup></code> | |||
The attack and decay scale members are expressed as 0.1% increments in 16.16 fixed-point. | |||
This may be converted to a normalized factor using: | |||
<code>scale / (1000.0 * 65536.0)</code> | |||
